The Fracture of Beil-tan was out a few weeks before the date give, the Rise of the Primarch after. Both now as obsolete as each other. It's a good idea but sucks that people buying something from the same campaign end up being treated differently.

They have to draw the line somewhere. They've already doubled their usual lead time on it, otherwise they might as well refund the whole of 7th edition, or every 6th edition codex that never got updated to a competitive level with its 7th edition peers.
